METHOD FOR FORMING FOVEOLAR FRAGMENT OF INTERNAL LIMITING MEMBRANE IN SURGICAL MANAGEMENT OF MACULAR OEDEOMA OF VARIOUS ETHIOLOGY Russian patent published in 2015 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: method involves performing 5-7 successive sets, each of which involves the following series of activities: an end of an internal limiting membrane (ILM) is separated from the retina at 2.0-2.5 mm to an inferiortemporal arcade from the foveola. A pair of pincers is used to take the ILM end, and to separate the membrane throughout 2 or 3 o'clock meridians by making a motion directed through a segment of an imaginary circle with its centre in the foveola. The retinal section at 1.0-1.2 mm from the foveola is checked to be intact. The ILM separated through the arch segment is embraced in the end point, which is followed by making a radial motion to separate the ILM stopping 0.5-0.8 mm short of the foveola. The ILM is embraced in the end point and separated throughout 2 or 3 o'clock meridians in the opposite direction. The above ILM portion is separated completely by making a radial motion terminated in the initial point. That ensures making an ILM foveolar fragment surrounding the foveola and enclosed by an ILM-free open-ring retinal area. The last ILM section is removed so as to avoid the ring closure. The remained intersection is elevated with using a pair of micro pincers by an end at an outer edge and separated in the central direction, stopping 0.5-0.8 mm short of the foveola, and the intersection is removed by means of a vitreotome.

EFFECT: reduced rate of injuries accompanying the surgical intervention, resorbed macular oedema, improved visual functions and preserved central vision.
